The best! All of the characters are great, actors amazing. There is adventure, drama, romance. It will not break your heart as historical dramas often tend to do.
I didn't like the lack of romance. It felt like there should have been sone, but the main characters act like kindergardeners. There is no passion between them.
I loved that the prince is oh so smart and a bit weird. Great characters, truly. And the story has everything - humour, drama, intrigue, romance. And what is most important to me - it does not break your heart.
I loved the fact that it stayed sweet enough till the end. There was some drama, but it does not start happy and sunny and then end in a tragedy like some shows.
Tragic ending - it is tagged so not a spoiler. The thing is, that there is no good reason for that kind of ending. None at all, since the series are very sweet and silly (a bit too much even). Anyway, not the best, not the worst.
